Speciflcation'of Letters Patent. Patented J 11 .1(; 1914,

Application filed March 18, 1913. Serial No. 755,201.

To all whom may concern! Be it known that I, RAPHAEL JAoonuoor, :itizen of the United States, residing at F all River, in the county of Bristol and State of Massachusetts, have invented certain new'and useful Improvements in. Multicolor-Printing Presses; and I do hereby detit) clare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appcrtains to make and use the same.

This invention relates to improvements in multicolor printingpressesyand an object of the invention is to provide a press .of this style where two or more different colors may be printed upon the same sheet without removing the sheet from the press.

A further object of the invention is to provide a press of this style with a platen which shall be adapted to hold the sheet to receive the impressions in approximately the same position.

A still further object of the invent-ibn is to provide a plurality of beds of type and aplaten intermediate adjacent beds, the beds of type being moved so that the platen 1s brought into contact with first one impression plate and then the adjacent impression plate.

A. further object of the invention is to provide a press of this style wherein the ink rollers remain stationary while the feeding mechanism and the impression plates are secured together andmove in unison.

A still further object of the invention is to provide means for positively actuating the platen and impression plates at all points of their travel. i

lVith these and other objects in view the invention comprises certain novel constructions, combinations, and, arrangements of parts as will-be hereinafter more fully described and claimed.

In the drawings: where like reference characters designate corresponding parts Figure 1 is a view showing the left hand side elevation of a machine embodying the invention... Fig. 2 is a view similar to Fig. 1 taken from the right hand side of the machine. Fig. 3 is a front elevation of the machine shown in Figs. 1 and 2; and Fig. 4 is a rear view similar to Fig. 8.

Machines the aims of which are to accom plish some of the general objects outlined above have been devised, but in some instances a plurality of impression plates described hereinafter.

have been secured upon a single member which is pivoted to assume different positions in order to register with a stationary platen, but insomuch as in the course of a run the impression plates will necessarily be reciprocated a great number of times considerable wear is occasioned at the bearing of the reciprocating memben. Further. more, presses of this type require that the bearing supporting the heavy moving member shall also be subjected to the strain accompanying the impression. In some instances gravity has been depended upon for returning the "impression plates to their lower position. The present invention aims to provide a moving member carrying a plurality of impression plates so disposed that the surface which takes the strain of the impression shall be large, and that the means used for reciprocating the impression plates shall be relieved of all strain during the impression; Also, suitable mechanism is provided for positively actuating the platen and impression plates so as to admit of no uncertainty in their movements.

In orderto explain the operationof the press, recourse will be had to the accompanying drawings, where it is to be understood that only one specific embodiment of the invention is shown, and that changes can be made in the specific means shown foractuating the ress without departing from the spirit of the invention.

In the drawings, where the impression plates are shown as moving vertically, the press is shown as composed of a pair of side plates 11 having bracing rods 2-2 connected to the legs thereof and provided with projecting arms 3, and bearing portions 4. Extending in an upright position from each of the side plates 1 -1 is a vertical track or way 5, the sides of which are parallel and adapted to guide the impression plates to be For the purpose of bracing the upper part of the machine there is extending between the two ways 5a suitable bolt 6 Journaled in the sides 1 is a rocker shaft 7 which may be formed integral with an arm 8 secured to a platen 9. If desiredthe arm 8 may. be cast integral with the platen 9 and may move about the rocker shaft 7 or have the supporting edges in the form of stub shafts. Extending from the platen and preferably cast integral therewith is a roller arm 10 adapted to carry a roller 11 which engages suitable cams for locking the platen 9 about the shaft 7. Journaled in the upper end of the projecting arms 3 on each of the sides'l-is a shaft 12, upon which is mounted a cam wheel 13 having formed therein a cam slot 1% for the purpose of en-' gaging roller 11. For the purp se f driving the cam wheel 13 there is.provided 011 the outer end of shaft 12 a beveled gear 15 adapted to engage a beveled pinion 16 carried by one end of the driving shaft 17 suit-- ably mounted on the frame 1. By means of the mechanism thus far-described it will be noted that by reason of the shape of the slot 14, the platen 7 will be reciprocated so as to move to and from the position of impression when the wheel 13 is rotated. a

In order to drive the shaft 17 there is journaled to the portions 4 of the frame a driven shaft 18 carrying a tight pulley 19, and a. loose pulley 20, these pulleys being engageable by any suitable belt or other driving mechanism. The shaft 18 carries a pinion 21 which engage a gear wheel 22 carried by shaft mounted in the portions 4t of the frame 1. Splined to the shaft 23 a beveled gear 2 1 which is adapted to engage a. beveled pinion 25 carried on the opposite end of the driving shaft from that carrying the pinion 16. From this it will be apparent that as the plate or other driving mechanism is drawn to the tight pulley 19 the shaft 23 will be rotated so as to actuate the wheel 13.

Adapted to reciprocate within the ways 5 is a plurality of impression plates 26, two being shown in the drawings. These impression plates may be made up in any of the approved forms at present in use, the particular form of the impression plate forming no part of th present invention. The impression lates 26 are mounted in car riers 27 which slidably engage the ways 5. the carrier 27 operating to prevent lateral movement of theimpression plate 26 as the whole reciprocate between the ways. For the purpose of reciprocating the carriers 27, which carriers are secured to a suitable frame, there is pivotally connected to the lower plate 26 a pair 'of'links 28 28 each of whichz 'is connected to an arm 29 feathered to a shaft 30 mounted in the sides, which has extendingtherefrom cars 31. A link 32 provided at its lower end with trunnions 33, which trunnions are journaled in the ears 3], i connected by means of other trunnions 31 to a lever pivoted to the side frame as at 36. The inner end of the lever 35 is provided with a roller 37 adapted to be received by a slot 38 formed in one side of the gea wheel 22. As shown in the drawings, the slot 38 is so formed that one revolution of the wheel 22 will result in an oscillation of the lever 35, the extreme down ward pomediately after the link 28 relation to the ways 5 cred necessary to be 1 1011.

sition of the roller 37 being simultaneous with the extreme downward position of the link 28 and impression plates-E6. The cam slots 38 and ll are so related to their respective rollers and actuated parts that imi .sumes its lowermost position the platen 9 will be forced inwardly upon the upper of the impression plates 26 and that as soon a the impression is completed and before the plates start on their upward moven'ient the platen will be removed. Immediately after the link 28 and the impression plates 26 assume their uppermost position the, platen will again be forced in to take the impressions from the. lower bed of type, the platen 9 being removed just before the impression plate starts on its downward movement. From this it will be seen that each time the impression plates are in an extreme position thatthe platen will be moved inwardly. In order to insure smoothness of operation there is provided a pair of springs 39 which is connected to one of the bracing rods 2. It is to be understood, of course, that the scope of this invention is not limited to the particular means for acuating the platen and impression' plates, nor is it limited. to the particular means for actuating the lovers controlling the movements of these While the ways for guiding the impression plates have been shown as vertical in the drawings, it is to be understood, of course, that tliG'StUIm may be horizontal or may be disposed at any convenient angle, these various modifications being accomplished by the necessary alterations in the particular driving mechanism without departing from the spirit of the invention.

The ink rollers in the present invention aredesigned to be stationary. To accomplish th1s result there are secured to each of the side plates 1 lugs -flO-l0, the ink rollers 4 141 being journalcd between the lugs 4040. These rollers are so disposed with that as the impression plates rise they will contact with the inking rollers. the impression plates passing over the rollers twice before coming into contact with the platen. tremities of the impression plate carriers 27 are inking plates 42-42, which may be of the usual form and may be provided with any approved actuating means not considshown in this applica- No particular means has been shown for furnishing the rollers with ink, insomuch asany one of a number of accepted mechanisms will work s:-itisfactorily with the present invention. Of course. to accomp sh the production of multi-color prints, the. upper inking rollers will be furnished with an ink colored differently from that furnished to the lower rollers, and the travel of the frame carrying the impression plates parts.-

Secured to the exwill be so regulated that no part of the lower impression, plate will come in contact with the upper inking rollers.

lVhile the invention has been described as being a twocolor press, yet it is obvious that in order to produce three or more color prints it would be necessary merely to extend the principles herein disclosed. Further, there have been shown but one platen and a pair of impression plates, but it will be entirely within the scope of the present invention to furnish the machine with a plurality of platens and a corresponding number of impression platesv From the description given, the operation of the parts will be apparent and it is not considered necessary to show or make mention of the attachments common. to

printing presses. It will be understood of course that the-mechanism herein described could also be used for the purpose of embossing or for giving single impressions, in which latter case the output of the machine would be double that when the machine is used for mnlti-colo-r impressions It Will be apparent that no matter what thearrange ment'of the impressions be the strain incident upon the impression will be transferred from the reciprocating parts to the ways 5 by means of the carriers 27, and that none of the impression strain is thrown laterally upon the driving rod 17 and the corresponding spur gears.
